i tried the new version and it says check for viruses and reinstall everytime.

Is that a problem with other RPG Maker games, or just with mine? It might be an overzealous anti-virus is marking the .exe file as dangerous. I don't think I changed anything significant from version to version, so I don't see why it should give warnings now. You can try downloading it from here, if it makes a difference (but I doubt it):

I would either disable the antivirus temporarily or exclude the file from scans, if you really want to play, but that's only if you trust this random developer you don't know personally. XD
I downloaded the files and installed the game just to make sure, so at least the problem shouldn't be with the uploaded files (windows defender did warn me because of the "unknown origins" of the file, but there is the option to install the game anyway afterward).
If the antivirus is flagging the game, it could also corrupt the download, so make sure to disable it before you start the download, install the game, and only then re-enable the antivirus.
